D300529 0115 - BL67 I/O modules
6-17
BL67-2AI-V, -10/0 … +10 VDC
6.3.2 Process data mapping
n = offset of input data; depending on extension of station and the corresponding fieldbus.
Process data Meaning
Data Byte Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Input n
AI0 LSB
n + 1 AI0 MSB
n + 2 AI1 LSB
n + 3 AI1 MSB
NOTE
With PROFIBUS, PROFINET and CANopen, the I/O data of this module is localized within the
proce
ss data of the whole station via the hardware configuration tool of the fieldbus master.
For DeviceNet, EtherNet/IP and Modbus TCP a detailed mapping table can be created with
the TURCK configuration tool I/O-ASSISTANT V3 (PACTware + BL67-DTM).
Table 6-8:
Process data bits
AI1 LSB low byte of the analog value
AIx MSB high byte of the analog value
